Grab Chrome Canary or a tip-of-tree Chromium Release build and launch it with the following flag (for help, see [1]):--enable-skia-benchmarking

Navigate to "about:tracing".

Open a new tab and navigate to your favorite knitting website.

Go back to the about:tracing tab and press record. Choose the "Frame viewer", or check “cc” and “cc.debug.display_items”. Uncheck everything else for this demo, then press record.

Go back to your knitting webpage and refresh the page. You can scroll around, select text, etc (each generated skpicture will be saveable).

Go back to “about:tracing” and press “stop tracing”.

Now for some fun! Use the W, A, S, and D keys like you’re playing a video game. Your goal in this game is to find the “cc::DisplayItemList” dot that you’d like to save. When you’ve found the one, click “Save SkPicture”. Note: you can use the left and right arrow keys to cycle through cc::DisplayItemLists. You may notice there are two copies of most pictures--this is for low resolution (first) and high resolution (second).
